See also:

animation:FlxAnimationController

Class that handles adding and playing animations on this sprite.

See also:

@:value(defaultAntialiasing)antialiasing:Bool = defaultAntialiasing

Controls whether the object is smoothed when rotated, affects performance.

@:value(0)read onlybakedRotationAngle:Float = 0

The minimum angle (out of 360°) for which a new baked rotation exists. Example: 90 means there are 4 baked rotations in the spritesheet. 0 if this sprite does not have any baked rotations.

See also:

blend:BlendMode

Blending modes, just like Photoshop or whatever, e.g. "multiply", "screen", etc.

clipRect:FlxRect

Clipping rectangle for this sprite. Changing the rect's properties directly doesn't have any effect, reassign the property to update it (sprite.clipRect = sprite.clipRect;). Set to null to discard graphic frame clipping.

@:value(0xffffff)color:FlxColor = 0xffffff

Tints the whole sprite to a color (0xRRGGBB format) - similar to OpenGL vertex colors. You can use 0xAARRGGBB colors, but the alpha value will simply be ignored. To change the opacity use alpha.

See also:

@:value(true)dirty:Bool = true

Set this flag to true to force the sprite to update during the draw() call. NOTE: Rarely if ever necessary, most sprite operations will flip this flag automatically.

@:value(RIGHT)facing:FlxDirectionFlags = RIGHT

Can be set to LEFT, RIGHT, UP, and DOWN to take advantage of flipped sprites and/or just track player orientation more easily.

See also:

@:value(false)flipX:Bool = false

read onlyorigin:FlxPoint

WARNING: The origin of the sprite will default to its center. If you change this, the visuals and the collisions will likely be pretty out-of-sync if you do any rotation.

pixels:BitmapData

This sprite's graphic / BitmapData object. Automatically adjusts graphic size and render helpers if changed.

read onlyscale:FlxPoint

Change the size of your sprite's graphic. NOTE: The hitbox is not automatically adjusted, use updateHitbox() for that. WARNING: With FlxG.renderBlit, scaling sprites decreases rendering performance by a factor of about x10!

read onlylast:FlxPoint

Important variable for collision processing. By default this value is set automatically during at the start of update().

@:value(1)mass:Float = 1

@:value(null)path:FlxPath = null

The path this object follows. Not initialized by default. Assign a new FlxPath() object and start() it if you want to this object to follow a path. Set path to null again to stop following the path. See flixel.util.FlxPath for more info and usage examples.

@:value(true)pixelPerfectPosition:Bool = true

Whether or not the position of this object should be rounded before any draw() or collision checking.

animated

Whether the Graphic parameter is a single sprite or a row / grid of sprites.

frameWidth

Specify the width of your sprite (helps figure out what to do with non-square sprites or sprite sheets).

frameHeight

Specify the height of your sprite (helps figure out what to do with non-square sprites or sprite sheets).

unique

Whether the graphic should be a unique instance in the graphics cache. Set this to true if you want to modify the pixels field without changing the pixels of other sprites with the same BitmapData.

key

Set this parameter if you're loading BitmapData.

Returns:

This FlxSprite instance (nice for chaining stuff together, if you're into that).

loadGraphicFromSprite(Sprite:FlxSprite):FlxSprite

Load graphic from another FlxSprite and copy its tile sheet data. This method can useful for non-flash targets.

Parameters:

Sprite

The FlxSprite from which you want to load graphic data.

Returns:

This FlxSprite instance (nice for chaining stuff together, if you're into that).

@:value({ AutoBuffer : false, AntiAliasing : false, Rotations : 16 })loadRotatedFrame(Frame:FlxFrame, Rotations:Int = 16, AntiAliasing:Bool = false, AutoBuffer:Bool = false):FlxSprite

Helper method which allows using FlxFrame as graphic source for sprite's loadRotatedGraphic() method.

Parameters:

frame

Frame to load into this sprite.

rotations

The number of rotation frames the final sprite should have. For small sprites this can be quite a large number (360 even) without any problems.

antiAliasing

Whether to use high quality rotations when creating the graphic. Default is false.

autoBuffer

Whether to automatically increase the image size to accommodate rotated corners. Will create frames that are 150% larger on each axis than the original frame or graphic.

Returns:

this FlxSprite with loaded rotated graphic in it.

@:value({ AutoBuffer : false, AntiAliasing : false, Frame : -1, Rotations : 16 })loadRotatedGraphic(Graphic:FlxGraphicAsset, Rotations:Int = 16, Frame:Int = -1, AntiAliasing:Bool = false, AutoBuffer:Bool = false, ?Key:String):FlxSprite

Create a pre-rotated sprite sheet from a simple sprite. This can make a huge difference in graphical performance on blitting targets!

Parameters:

Graphic

The image you want to rotate and stamp.

Rotations

The number of rotation frames the final sprite should have. For small sprites this can be quite a large number (360 even) without any problems.

Frame

If the Graphic has a single row of square animation frames on it, you can specify which of the frames you want to use here. Default is -1, or "use whole graphic."

AntiAliasing

Whether to use high quality rotations when creating the graphic. Default is false.

AutoBuffer

Whether to automatically increase the image size to accommodate rotated corners. Will create frames that are 150% larger on each axis than the original frame or graphic.

Key

Optional, set this parameter if you're loading BitmapData.

Returns:

This FlxSprite instance (nice for chaining stuff together, if you're into that).

@:value({ Unique : false, Color : FlxColor.WHITE })makeGraphic(Width:Int, Height:Int, Color:FlxColor = FlxColor.WHITE, Unique:Bool = false, ?Key:String):FlxSprite

This function creates a flat colored rectangular image dynamically.

HaxeFlixel's graphic caching system keeps track of loaded image data. When you make an identical copy of a previously used image, by default HaxeFlixel copies the previous reference onto the pixels field instead of creating another copy of the image data, to save memory.

NOTE: This method updates hitbox size and frame size.

Parameters:

Width

The width of the sprite you want to generate.

Height

The height of the sprite you want to generate.

Color

Specifies the color of the generated block (ARGB format).

Unique

Whether the graphic should be a unique instance in the graphics cache. Default is false. Set this to true if you want to modify the pixels field without changing the pixels of other sprites with the same BitmapData.

Key

An optional String key to identify this graphic in the cache. If null, the key is determined by Width, Height and Color. If Unique is true and a graphic with this Key already exists, it is used as a prefix to find a new unique name like "Key3".

Returns:

This FlxSprite instance (nice for chaining stuff together, if you're into that).

@:value({ alphaTolerance : 0xFF })pixelsOverlapPoint(worldPoint:FlxPoint, alphaTolerance:Int = 0xFF, ?camera:FlxCamera):Bool

alphaTolerance

Used to determine what counts as solid.

camera

The desired "screen" coordinate space. If null, FlxG.camera is used.

Returns:

Whether or not the point overlaps this object.

@:value({ FetchPositions : false })replaceColor(Color:FlxColor, NewColor:FlxColor, FetchPositions:Bool = false):Array<FlxPoint>

Parameters:

Color

Color to replace

NewColor

New color

FetchPositions

Whether we need to store positions of pixels which colors were replaced.

Returns:

Array with replaced pixels positions

The cameras that will draw this. Use this.cameras to set specific cameras for this object, otherwise the container's cameras are used, or the container's container and so on. If there is no container, say, if this is inside FlxGroups rather than a FlxContainer then the default draw cameras are returned.

Available since

5.7.0

.

kill():Void

Handy function for "killing" game objects. Use reset() to revive them. Default behavior is to flag them as nonexistent AND dead. However, if you want the "corpse" to remain in the game, like to animate an effect or whatever, you should override this, setting only alive to false, and leaving exists true.

revive():Void

Handy function for bringing game objects "back to life". Just sets alive and exists back to true. In practice, this function is most often called by FlxObject#reset().
